Deployment method and computer system for network system

The present invention relates to a method for deploying a network system, and more particularly to a method for deploying a network system including an IPv4 packet and an IPv6 packet.

With the rapid development of network and Netcom equipment, most people access a variety of network services through a gateway and a transmission channel, such as a cable TV, xDSL, fiber or wireless network. . Preferably, the Netcom device that integrates the cable data machine and the gateway device is configured to appropriately allocate an IP address to different users through a Dynamic Host Configuration Protocol (DHCP), and the user The configured IP address takes Time of Day (ToD) and its profile for data machine and gateway configuration.

However, with the explosive development of various network services, the IPv4 address that has been traditionally used has been exhausted, and the IPv6 address has been redeployed. However, the process of converting from IPv4 address to IPv6 address, for the packet originally transmitted using only IPv4 address, has been proposed, for example, to encapsulate the IPv4 packet with IPv6 header (ie IPv4-in-IPv6). Transmitted to be compatible with the new IPv6 address. In addition, there are also known techniques for wrapping IPv6 packets in IPv4 headers (ie IPv6-in-IPv4) for use in Netcom devices that have not been updated to resolve bits. The transition period of address conversion, but the above method is inefficient, and it is not easy to deal with the problem of packet segmentation, resulting in network transmission performance (Throughput) low.

Therefore, another deployment method for a network system is provided, which can simultaneously transmit transmission data including IPv4 packets and IPv6 packets, and solve the problem of packet segmentation in the transmission data, thereby improving network transmission performance, and has become An important topic in the field.

Therefore, the main purpose of the present invention is to provide a method for deploying a network system, which can simultaneously transmit transmission data including an IPv4 packet and an IPv6 packet, and can solve the problem of packet segmentation in the transmission data.

The present invention discloses a method for deploying a network system, the network system including a gateway, a near-end server, and a remote server.

Please refer to FIG. 1. FIG. 1 is a schematic diagram of a computer system 10 and a network system 20 according to an embodiment of the present invention. As shown in FIG. 1, computer system 10 includes a central processing unit 100 and a storage device 102. The storage device 102 stores a code (not shown) for instructing the central processing unit 100 to execute a deployment method for the network system 20 to provide a user with the computer system 10 from the area through the network system 20. The Internet connects to an Internet NT and performs common web browsing, transferring electronic files, and sharing and communicating with the social network. The network system 20 includes a gateway 12, a transmission device 14, a near-end server 16, a remote server 18, and an Internet NT. In this embodiment, the deployment method establishes a transition transmission channel between the gateway 12 and the remote server 18, so that the computer system 10 can transmit the data including one of the IPv4 packet and one of the IPv6 packets through the network system 20. .

In detail, the gateway 12 has integrated a network authentication function of a cable modem to provide a connection between the computer system 10 and the Internet NT. The transmission device 14 is a data machine, for example, a cable data machine, a fiber data machine or an xDSL data machine. The near-end server 16 is a Trivial file transfer protocol (TFTP) server, and the remote server 18 is a tunnel server, for example, a Dynamic host configuration protocol (DHCP) v6. The server of the Option_AFTR_NAME (64) protocol. In addition, the transmission device 14 and the remote server 18 perform related transmission operations through the Internet NT. However, the connection between the gateway 12 and the near-end server 16 is not limited, and in the present embodiment, the Internet NT is used to transmit IPv6 packets, but is not intended to limit the scope of the present invention. .

Of course, the transmission format can also be used to support communication protocols such as Option_AFTR_NAME (64) of DHCP v6. Since the Internet NT is used to transmit IPv6 packets, in this case, when the computer system 10 wants to transmit IPv4 packets, the gateway 12 adds an IPv6 packet header to the IPv4 packet to form an IPv4-in-IPv6 packet. The IPv4-in-IPv6 packet is transmitted to the remote server 18 through the transition transmission channel between the gateway 12 and the remote server 18. Preferably, the transition channel between the gateway 12 and the remote server 18 is not limited to transmit IPv4-in-IPv6 packets, and those skilled in the art may also provide configuration data according to the embodiment. The different Internet used in the network system 20, for example, the Internet for transmitting IPv4 packets, is configured by the gateway 12 to appropriately add the IPv6 packet sent by the computer system 10 to an IPv4 packet header. Another IPv6-in-IPv4 packet, which is then transmitted by the transition transmission channel, is also within the scope of the present invention.

In other words, the transition transmission channel provided in this embodiment can be configured to pre-complete the transition transmission according to the user's needs or the type of the Internet.

Of course, those skilled in the art can appropriately match different switching mechanisms/control signals, so that the gateway 12 can dynamically switch to the operation of transmitting IPv4-in-IPv6 packets or transmitting IPv6-in-IPv4 packets, or It is also within the scope of the present invention to simultaneously establish a plurality of transition transmission channels between the gateway 12 and the remote server 18 for simultaneous/individual transmission of IPv4-in-IPv6 packets and IPv6-in-IPv4 packets.

In addition, the transition transmission channel provided in this embodiment can also use one input interface (not shown) of the computer system 10 to set the gateway 12 and the remote server 18 according to different needs of the user. The amount of data transferred between. In this case, the established transition transmission channel further includes a Maximum Transmission Unit (MTU) data, corresponding to the size of the transmission data between the control gateway 12 and the remote server 18, thereby determining the transmission data (ie, IPv4). A maximum segment size (MSS) data for a packet or IPv6 packet. Please refer to FIG. 2, which is a schematic diagram of determining the size of the transmission data in the transition transmission channel according to the embodiment of the present invention. As shown in FIG. 2, a terminal A (ie, computer system 10) first transmits a synchronization packet SYN<MSS _A >, which includes one of the maximum segment size data MSS _A applicable to the terminal A. After being processed by the gateway 12, the synchronous packet SYN<MSS _A > will be modified by the gateway 12 into a synchronous packet SYN<MSS _HG >, which contains one of the maximum segment size data MSS _HG applicable to the gateway 12 . Then, after receiving the synchronization packet SYN<MSS _HG >, a terminal B (that is, the remote server 18) returns a synchronization packet SYN<MSS _B >_ACK, which includes one of the maximum points applicable to the terminal B. The segment size data MSS _B and also contains a confirmation signal ACK. After being processed by the gateway 12, the synchronization packet SYN<MSS _B >_ACK will be modified by the gateway 12 into a synchronization packet SYN<MSS _HG >_ACK, which contains the maximum segment size to which the gateway 12 is applied. Data MSS _HG and confirmation signal ACK. Finally, after receiving the synchronization packet SYN<MSS _HG >_ACK, the terminal A will return the acknowledge signal ACK through the gateway 12 to the terminal B, thereby establishing the connection between the gateway 12 of the computer system 10 and the remote server 18. The three-way transmission also completes the transmission data size suitable for setting the transition transmission channel between the gateway 12 and the remote server 18.

In addition, the transition transmission channel provided in this embodiment may perform a segmentation operation on the IPv4-in-IPv6 packet or the IPv6-in-IPv4 packet in the transmission data according to different needs of the user. Please refer to FIG. 3, which is a schematic diagram of the segmentation operation of the transmission data according to the embodiment of the present invention.
